Video Memory Interface 
The memory controller subsystem of the Rage XL arbitrates requests from direct memory 
interface, the VGA graphics controller, the drawing coprocessor, the display controller, the video 
scalar, and hardware cursor. Requests are serviced in a manner that ensures display integrity 
and maximum CPU/coprocessor drawing performance. 
The Server Board SE7520JR2 supports an 8MB (512Kx32bitx4 Banks) SDRAM device for 
video memory. The following table shows the video memory interface signals:
